To all whom it may concern:

e it known that l, WILLJAM CLARK, a citizen of the United States, residing at Shaker lieip hts Village, in the county of Cuyahoga and State of Ohio, have invented a new and useful Machine for Heading Up Barrels, o1 whichthe following is a specification.

T his invention relates to improvements in machines for heading up barrels, and pertains more especially to a machine adapted to be employed in heading up an upright open barrel comprising staves in the formation of its body to the upper portion of which a barrel-head and a head-hoop areto be applied.

My improved machine comprises a cable for encircling the upper portion of said barrel preparatory to driving said hoop into place, a substantially vertically movable slide suitably spaced upwardly from the barrel-receiving base, means for actuating the slide, a hoop-driving head supported from and movable with the slide and having a movement independent of the slide and adapted, when it is in position at one end of its independent movement in the upper position or" the slide, not only to descend with the slide but to drive the aforesaid hoop into place during the descent of the slide, and means whereby the aforesaid cable, upon placing it into its barrel-encircling position preparatory to the descent of the slide, is tightened, during the descent of the slide and betore the hoop-driving operation, in relation to the staves of the barrel so as to ti hten the staves in relation to the aforesaid barrel-head.

)ne object of this invention is to provide my improved machine with a hoop-driving head which has a substantially horizontal movement independent of the slide supportin; said head and is manually movable out oitlie way of an upright open barrel to be placed in the required position for receiving a barrel-head and the head-hoop to be driven into place.

Another object is to have the hoop-driving head positively and accurately drive the head-hoop into place during the descent of the slide.

Another obje t is to have the machine comprise e iici and reliable means wherebv. dnrino; the descent of the slide and before driving the head-hoop into place, the

barrel-encircling cable is tightened in relation to the barrel-staves so as toltighten the staves in relation to the barrel-head.

Another object is to render a'inachine of the character indicated simple, strong and durable in construction and reliable in its operation, and to facilitate the operationsto be performed by the movable parts of the machine. I i

lVith these objects in view, and to attain any other object hereinafter appearing, this invention consists in certain featuresoi construction, and combinations and relative arrangements of parts, hereinafter described in this specification, pointed out in the claims, and illustrated in the accompanying drawings.

In said drawings, Figure l is a front View, partly in section, oi my improved machine forheading up barrels. Fig. 2 is a central section takenalong the line 22 in Fig. 1. 3 is a horizontal section taken along the line 33 in Fi 2. Figs. 4 and 5 are vertical sections ta en along the line 4-4 and line 5-5, respectively, in Fig. 2, looking rearwardly. Fig. dis a horizontal section taken along the line 66 in Fig. 1, except that Fig. 6 shows an open barrel mounted onthe base'ot themachine. Fig.7 is a view similar to Fig. 6, except that Fig. 7 shows the barrel accurately positioned on said base and shows the upper end of the barrel supplied with a head and head-hoop which is to be driven into place. Fig. 8 is a view similar to Fig. 2, except that Fig. 8 shows the hoopdriving head actuated into its forward position and in line vertically with an accurately positioned barrel loosely embraced bv the hereinbeiore mentioned cable and also shows a head-hoop in position to be driven into lace. Fig. 9 shows a'portion of Fig. 8. but in 9 the hoop-driving head is shown lowered into proximity to the headhoop,to be driven into place during the l-"scent oi the hereinbeiore mentioned slide. 151'. 10 is a vertical section taken along the line lll--l0 in Fig. 8, looking rearwardly. ll. is a vertical section taken along the line 1l-11 in F 9, looking rearwardly. Fig. 12 is a view similarto butdrawn on a larger scale than 9', except-that the head-hoop is shown as driven into place in 12. Fig. 13 is a vertical section taken alone: the line 1313 in Fig. 12. Portions are broken away in the drawings to reduce their size and to more clearly show the construction, and Figs. 12 and 13 are drawn on a larger scale than the other figures.

Referring to said drawings, 15 (see Figs. 1, 2 and 3) indicates two laterally spaced and oppositely arranged vertical metal standards which are mounted on and secured to and rigid with a horizontal metal plate 16 having the dimensions required to render it capable of serving as a base on wh1ch a barrel, to which a head and a headhoop are to be applied, may be mounted on end, and said standards are far enough apart to permit said barrel to be placed in the space between the lower portions of the standards and in position to receive said head and said hoop from above. Said standards extend a suitable distance above the base 16 and are tied together at their upper ends by a metal cross-bar 17 secured to the standards in any approved manner. The upper portion of each standard 15 isprovided, at the inner side of the standard, with a laterally and inwardly projecting and guideway-torming vertical rib 18, and the ribs 18 of the standards are directly opposite and parallel. The rib 18 of each standard engages a groove 19 formed in and extending vertically through the adjacent end portion of a substantially vertically movable slide 20 which extends between the upper end portions of the standards and is supported from a substantially vertical screw 21 employed in actuating'said slide. Said screw is arranged centrally between the ends of and threaded into and extends through the slide 20 and also extends through and has lateral bearing in the cross-bar 17 from which said screw is supported; Said screw is provided, next the under side of the bar 17, with an upwardly facing annular shoulder 22 which cooperates with said bar in preventing upward endwise movement of the screw. Arranged over and resting on the central portion of the bar 17 is a bevel- ,e'ear 23 which is operatively mounted on the screw 21 in any approved manner. The screw 21 extends above the gear 23, and a nut 25 is threaded onto said screw next above said gear and cooperates with said gear in preventing downward endwise movement of the screw. It will be observed therefore that the screw 21 is held against endwise movement during the roration of the screw and that the slide 20 is lowered or elevated according as said screw is rotated in the one or the other direction. The bevel-gear 23 constitutes a member of the mechanism employed in operating the screw 21 and meshes with a bevel-pinion 26 operatively mounted on a horizontal shaft 27 which is spaced substantially vertically upwardly from and parallel with the cross-bar 17 and rotated in any approved manner in the one direction or the other as may be required. 'Means for rotating a shaft a predetermined extent in the one or the other direction, and means for controlling the operation of screw-rotating mechanism, are too well known in the art to require illustration and description in this specification.

The slide 20 (see Figs. 2 and 3) has a rearwardly projecting horizontal frame 29 hereinafter referred toand is provided, at

1, 2, 3 and 4) is provided at the bottom with a laterally and inwardly projecting substantially horizontal flange 32 which ex ends longitudinally of the bar and therefore projects toward and is spaced from the corresponding flange 01" the other of said bars. The flanges 32 of the bars 30 form a track from which the hoop-driving head of my improved machine is supported, and said head has an interiorly chambered body 33 and has its hoop-engageable face formed by a substantially horizontal metal plate 3 1- secured to and rigid with said body, and 35 indicates the interior chamber of said body. The body 33 of the hoop-driving .head extends between the track-forming flanges 32 of the bars 30 and is provided with two rollers 36 ar ranged at opposite sides respectively or" said body and each resting on the adjacent flange 32. It will be observed'therefore that the slide 20 forms a movable support tor and extends over the hoop-driving head and is provided with a track arranged at the under side and transversely of the slide and extends rearwardly from within the space between the standards 15, and that said head has an independent movement endwise of the track-forming flanges 32, and consequently from its rearward and inoperative position shown in Figs. 2 and 3 into its forward position shown in Fig. 8., and vice versa, and the relative arrangement of the parts is such that the tops of the rollers 36 are slightly lower than the top of the body 33 of the hoop-driving head, and that said body, when the slide 20 is in its upper position shown in Figs. 1, 2, and 8,.is somewhat spaced downwardly from the slide. Also, the body 33 is provided, at the front of its lower portion, with a handle 37 for convenience in manlot) ually shifting the hoop-driving head endwise of the track-forming flanges, 32.

On the tlange 32 of each bar 30 (see Figs. 1, 3, 4, 8, 9 and 12) are mounted two stopetorming members 38 and 39 arranged at the forward end and rearward end re spectively of and secured in any approved manner to said flange. The length of the bars 30 and the relative arrangement of the parts are such that the rollers 36 of the hoopdr' ing head abut against the rearward stop-forming members 39, or against the forward stop-forming'members 38, accordas said head is in its rearward position shown in Figs. 1, 2 and 3, or in its forward position shown in'Figs. 8 and 9; that said head, in its rearward position, is rearwardly out of the way of the barrel-receiving space between the lower portions of the standards 15 and, in its forward position, is over said space,and that said head, when it is at the forward end of its independent movement in the upper position of the slide, is adapted to be lowered the extent required to drive a headhoop into place during the required descent of the slide, and obviously the lowered hoop-driving head, during the return of the lowered slide into its upper position, is elevated from a head-hoop driven into place by said head.

l-learward moven'icnt of the barrel on the platform-forming base 16 (see Figs. 1, 2 and 6) is limited by the rearwardly curved central portion of a metal bar which has opposite end portions l-Q. thereof secured to opposite standards 15 respectively, and two barrehguiding and barrel-positioning members 43 are pivoted vertically, as at -l5, to said bar at the inner end at opposite end portions respectively of the bar and extend {oi-w rdly from their axes and circumferially 0t oppos'te sides respectively of the barrel-receiving space between the lower portions of the standards 15. Each barrelpositioning member 42 has a laterally and inwardly projecting arm l6 rearward of the axis Oi said barrel positioning member, and the arms ell; or" said members 43 project toward ach other and are spaced laterally at their free ends. l 6 shows an upright open wooden barrel B comprising stares in the formation of its body and mounted on the base 16 and arranged between the barrelpo iioning members as. and the relative arnent of the parts i s such that the abutrming member ll and the arms to ou at the rear oil the upper pon the barreirec ingspace, and that oairel, during slnitrng of the barrel 'i'roin the position shown in Fig. '6 rear wardly into the position shown in Figs. 7 and 8, and consequently against the abutment-member 4:1, swings said arms rearly and thereby actuates the barrel-positioning members 43 into a position in which said members as embrace the barrel and insure accurate positioning of he barrel on the base 16.

Rearward of the lower end of each stand ard 15 (see Figs. 2, 3 and 6) is a metal plate 4'? mounted on the base 16 to which said plate is rigidly secured in any approved manner, and said plate has two upwardly projecting flanges 48 formed at the rear end and forward end respectively of the plate, and a horizontal pivotal pin d9, arranged substantially at a right angle to the axes of the rollers 36 of the hoop-driving head, has bearing in said flanges and forms the fulcrum of a lever 50 which .is arranged rear ward of the adjacent standard 15 and extends from said pin upwardly to a point above the slide 20. A coiled spring 51 (see Fig. 10) extends between the upper ends of the levers 50 and is attached to said levers in any approved manner.

The screw 21 extends below the slide 20 in the upper position of the slide, and a flexible cable is arranged under said slide and has its central portion in the form or" a loop 53 which (see Figs. 1 and 2) leans against the rear side of the lower end of said screw, and opposite end portions 5% and 55 of said cable cross each other adjacent the free ends of the arms 4-6. Said cable (see Figs. 1, 5 and 6) has its end portion 54, which extends from the left-hand side of the loop 53, leading toward and operatively connected with the lever 50 behind the standard 15 at the left-hand side of the machine, and the cable has its opposite end portion 55, which extends from the righthand side of said loop, leading toward and operatirely connected with the lever 50 be hind the standard 15 at the right-hand side of the machine. Preferably the operative connection between each end portion of said cable and the lever 50 toward which said end portion of the cable leads shown as comprising a substantially horizontal eye-bolt arranged substantially at a right angle to the axis of said lever and having its eye 57 opposite and spaced from the laterally inwardly facing side of said lever and attached in any approved manner to said end. port'on of the cable, and said bolt has its shank 58 extending loosely through the lever and beyond the laterally outwardly facing side or the lever, and a nut 59 is threaded onto said shank at and abuts against the last-mentioned side of the lever so that any lateral outward movement of the lever will result in the exertion of pressure by the lever against the inner end. face of said nut and thereby pull on the connected end portion of the cable. Obviously the barrel-encircling cable is tightened in relation to the barrel by simultaneously swinging the levers 5O laterally outwardly.

The barrel B, shown mounted on the to be driven downv' l igs. l and 10) is provi-i .l

ready been heated l-hoop e2 is mounted on the upper end 0' the barrel and in position i into place, and thereupon the hoop-d g head while the slide'QO is or remains in its upper position, actuated forwardly from its rearward and inoperative position, shown in Figs. 2 and 3, into its :tcrward position shown in Fig. 8, where screw 21 is rotated in the direetlo: t 1e extent required to lower the slide far enough to result in driving said hoop (52 in Fig. 12. The body 33 ot tl e hoop-clriving head (see Figs. 1, 2, and 8) is proand top tiereoi, with as required to pernut vided, at the :front slot 35 arranged lCl body to clear movement of the hoop-driving head from its rearward position shown in Figs 1 and 3 into its forward position shown in Fig. 8. Fig. 9 shows the hoop-driving head as having come into close proximity to but not yet into contact with the head-hoop (32 dun ing and before the completion of the do scent of the slide. and obviously the hoopdriving head, upon coming into event with said hoop during said descent of the slide, will inon'ientarily cease to descend until the slide during its said descent abuts against the top ot the body of the hoopdriving head and drives the hoop-thriving head downwardly ward movement of the hoop-driving head so as to result in the driving of said hoop into place "howu in Fig. 1 u oiicourse, the rotation otthe screw Qi is arrested and as said hoop has been driven into place.

The upper portion of each lever (see u at re laterally inwardly facing side i the lever, with an upwardly and laterally inwardly facing incline 63'which terminates at its lower end in a laterallyinwardly facing surface (i l extending downwardly lron'i the lower end of said incline and formed on said lever at said side of the lever. The rearwardly projecting frame or member 29 of the slide 20 (see Figs. 2, 3, 8, 9, 10, 11, 12- and 13) is provided, adjacent each ever 50, with substantially horizontal roller 65 which is substantially parallel with the axis of the lever, and the relativearrangement of the parts is such that said roller, in th upper position of the slide engages the incline 63 on sald lever'as shown in Figs. 1 and 10 and the lower end or into place as shown,

the screw 21' during 1 1 i try, against to complete the down cooperates w h said incline in actuating said lever al scent of the slide, and that said roller, 111 said des ent oi the alide, comes into ie'nient with the surface G l of said as shown in Fig. 1.1, before the slide has come into its lower position shown in Big. 13, and that said roller is in engage men; with said surface Gelinthe last-mew tioned position of the Sllfle. Preferably the love =30 in their inner position, shown in Figs. 1 and 10, tip somewhat toward each other so to assist the spring in the retention of the levers in contact with the rollers (55.and the relative arrangement of the parts is such that in said position or the levers their surfaces diverge somewnat downwardly, and that in the outer position of the levers, as shown in Figs. ll and 13, said surfaces'are substantially vertical. The loop of the cable,'upon its application to barrel as shown 7 and S, is loose in relation to the bar Obviously the rollers 65 carried by' slide 20 and the inclines 63 on the levers constitute means whereby the levers siinultaneoiisly actuated laterally outwardthe action of the spring 5l,dur ing downwmd travel ofthe slide, and 0bviously the loop 53 of the cable is'reduced in size diametrically during said actuation of the let so that the barrel-encircling cable is tightened as required. in relation to the barrel-saves so as, "to tighten said staves in. relation to the barreleheadfil and vreliably secure said head in place, as shown in Fig. 9, before the hoop-driving head has come into engagement with the head-hoop t flduring the descent of the slide.
